The Luminosity Function of the Coma Cluster Core for -25
We determine the luminosity function (LF) of galaxies in the core of the Coma cluster for M_R<=-11.4 (assuming H_0=75 km/s/Mpc), a magnitude regime previously explored only in the Local Group.Expand

A catalog of digital images of 113 nearby galaxies
We present a digital catalog of images of 113 galaxies in this paper. These galaxies are all nearby, bright, large and well resolved. All images were recorded with charge coupled devices (CCDs) atExpand

The triple QSO PG1115 + 08: another probable gravitational lens
Recently, Walsh, Carswell and Weymann1 reported the discovery of two objects (0957+56A,B) with identical spectra and separated by 6 arc min. They suggested that a gravitational lens was responsible.Expand

The clustering of faint galaxies
Deep images of the sky reveal a population of faint blue objects that may be protogalaxies at redshifts of more than approximately 1. The faint galaxies are surprisingly weakly clustered. There areExpand

Deep CCD survey - Galaxy luminosity and color evolution
Imaging and photometric observations of a statistically complete sample of galaxies in 12 high-latitude fields, obtained in the BJ (360-520 nm), R (580-720 nm) and I (780-1100 nm) bands using CCDExpand

The Mass Distribution of the Most Luminous X-Ray Cluster RXJ 1347.5-1145 From Gravitational Lensing
Galaxy cluster mass distribution are potentially useful probes of $\Omega_0$ and the nature of the dark matter. Large clusters will distort the observed shapes of background galaxies throughExpand

Measurement of the mass profile of abell 1689
In this letter we present calibrated mass and light profiles of the rich cluster of galaxies Abell 1689 out to 1 $h^{-1}$ Mpc from the center. The high surface density of faint blue galaxies at highExpand

Discovery of a Galaxy Cluster via Weak Lensing
We report the discovery of a cluster of galaxies via its weak gravitational lensing effect on background galaxies, the first spectroscopically confirmed cluster to be discovered through itsExpand

Unlensing Multiple Arcs in 0024+1654: Reconstruction of the Source Image
A unique reconstruction of the image of a high-redshift source galaxy responsible for multiple long arcs in the z = 0.4 cluster 0024+1654 is obtained by inverse lensing. Deep B- and I-band imagingExpand

First Results on Shear-selected Clusters from the Deep Lens Survey: Optical Imaging, Spectroscopy, and X-Ray Follow-up
We present the first sample of galaxy clusters selected on the basis of their weak gravitational lensing shear. The shear induced by a cluster is a function of its mass profile and its redshiftExpand
